I guess the problem does NOT relate to IconDatabase::syncThreadMainLoop(), it's a classical problem:

QtWebKit uses a blocking socket for under networking, if the network or server blocks/delays, it will cause GUI client to blocked.

The root solution is to use a non-blocking socket for client QtWebKit, but i hesitate whether it needs big modification?

Perhaps i could use bool QAbstractSocket::waitForReadyRead(int msecs = 30000) to fix this, But due to https://bugreports.qt-project.org/browse/QTBUG-24451 , waitForReadyRead is also not reliable.

So, how to ```non-blocking``` in QtWebKit's network part code?
